There will also be a sausage sizzle and the triple J Hottest 100 streaming in the courtyard. Then at 6.30pm, the Canberra premiere of the NFSA's digital restoration of Starstruck (1982) is screening, with a special Q&A with director Gillian Armstrong.

You can get an all-day pass, which will give you access to all of the screenings for $20, or individual tickets are available. Tickets at nfsa.gov.au.

We have three double all-access passes to give away, which will each give you access to all four films.
